14.19 Air leakage check

1) After the air conditioner connection is

completed, run the unit in fan condition.

2) You must check for air leakage in the

flexible duct and duct connecting part.

3) In case of air leakage

(1) Tighten the connecting part of the duct to

stop the leakage.

(2) Recheck for leakage in the connecting

part or parts where leakage can occur.

(3) If there is no leakage, proceed to the next

work phase.
